GE Mark VI Series IS200VTURH1B Main Turbine Protection Plate

The IS200VTURH1B is GE's main turbine protection plate for the Mark VI system.

The Mark VI is one of several gas/steam turbine management systems released by GE as part of the “Speedtronic” family.

The MKVI is built on a TMR (Triple Modular Redundancy) architecture and features a connected HMI (Human Machine Interface) that allows the user to access turbine data from a central location.

The IS200VTURH1B provides a variety of functions including monitoring the sensing shaft current/voltage (overshoot alarm), the

measuring turbine speed to generate a primary overspeed trip, and controlling the three primary overspeed trip relays belonging to the TRPx terminal board.

The board also monitors eight Geiger-Mueller flame detectors on the gas turbine.

The IS200VTURH1B has an attached single-slot panel with three LED indicators and a cable connector (J5).

The panel is connected to the PCB by three screw connections. the PCB consists of more than 60 integrated circuits, 13 transistors, hundreds of capacitors and resistors, as well as diodes and inductive coils.

The board has two backplanes, a multi-position female plug for connecting daughter boards, and several connectors made of conductive dots and traces.

The board is factory drilled in several locations to provide mounting options, including four holes for standoffs to support the previously mentioned daughter boards.

The board is labeled with codes such as 6BA01. 94V-0. and Type 6.

See the Mark VI Turbine Control System Guide (GEH-6421) for more information on the operation, installation, and function of the IS200VTURH1B.

Reliability

The IS200VTURH1B board is very reliable and therefore not easily damaged. However, improper handling and storage can affect the functionality of the card. We therefore recommend storing the card in a static-sensitive storage box under the recommended conditions.

Repair

If you experience any problems with the IS200VTURH1B, we can quickly test, diagnose and fix them.

The Expedite Repair option is available for the IS200VTURH1B. these cards are repaired in a controlled environment using the appropriate tools and specialists.

All the parts needed to repair this board are in our inventory. We also ensure that the replacement components are industrial grade and meet or exceed OEM standards.FVT tests all repairs and offers a warranty.

Refurbishment

Properly refurbishing your IS200VTURH1B circuit board can extend its useful life.

The refurbishment process includes:

Replacing all deteriorated and commonly failing components.

Applying TIL modifications (if any).

Reflow solder to eliminate dry solder.

Thorough industry standard cleaning of the card.

Application of protective coatings, etc.

Functional Verification Testing

We perform functional verification testing of the IS200VTURH1B in an actual OEM system setup.

By using an OEM system, we can guarantee 100% reliability. As with any other card, all inputs and outputs are individually verified for functionality.

Therefore, each channel is individually verified. Depending on the board, load tests are performed to ensure proper board stability.

Board Handling.

The IS200VTURH1B is a static sensitive board.
